Scores of ideas were tried, some discarded and others developed. All this necessitated many tests, the burden of which fell on Ludlow. The problems of gear ratio, spark lead, carburetion, compression, fuel, valve timing, piston clearance, all were worked out by tests and analysis of results. Progress was slow at times but it was steady and when a short sprint near the Palisades showed 123 miles an hour, it was decided to seek a long course and make another official trial. Today’s record is the result.
